Controls, Skins, CSS and Custom "psuedoclass" (beyond :hover, :pressed...)

Question

Hi All,
If you haven't experienced control skinning via css, read about it here: http://forums.sun.com/thread.jspa?threadID=5357325&tstart=0 (thanks to tamerkarakan).
Turns out Control has some stateful information stored in it such as hover, pressed, focused. When these are TRUE you can associated a style with that stateful presence of your Control.
The CSS to turn MyControl from RED to GREEN when hover is (programaticaly) set to true would look something like:
"com.myjavafxapp.control.MyControl" {
fill: RED;
"com.myjavafxapp.control.MyControl":hover {
fill: GREEN;
}What I would like to know is can I add my own "hover" equivalent? If I create a control that has stateful setting of "state"="Low:Medium:High" and I want these represented in the CSS by "Yellow, Orange, Red" how can this be done? Ideally all styling logic should be outside the control in JavaFX CSS. What I would really like to see from a CSS perspective is this....
"com.myjavafxapp.control.MyControl" {
"com.myjavafxapp.control.MyControl":state=low {
fill: YELLOW;
"com.myjavafxapp.control.MyControl":state=med {
fill: ORANGE;
"com.myjavafxapp.control.MyControl":state=high {
fill: RED;
}Can this be done?
Cheers

Thanks topley, that's what the fan's want alright.
According to that I need...
"com.myjavafxapp.control.MyControl":${state == LOW} {
fill: YELLOW;
"com.myjavafxapp.control.MyControl":${state == MED} {
fill: ORAGE;
"com.myjavafxapp.control.MyControl":${state == HIGH} {
fill: RED;
}But this css syntax is NOT supported in JavaFX :'( and neither is :state==High or :state=High eta. I tried adding state as a boolean and just :state {} but this gives the following exception....

Things would probably be a little easier for me to work out if I could look at the source of Control and determine how hover, pressed and focused are implemented... even if I am limited to just discrete Boolean values for now.
